What it means
In UBL, the check limits cac:BillingReference/cac:InvoiceDocumentReference/cbc:ID to 35 characters within each cac:InvoiceLine or cac:CreditNoteLine. Spaces count towards the limit.
Why it matters
The French rules set this length limit for invoice references on individual lines. The reference must fit the limit without losing the identity of the original invoice.
How to fix it
Find the affected line's cac:BillingReference/cac:InvoiceDocumentReference/cbc:ID and compare it with the original invoice number. Remove any labels or comments added to the reference, but keep characters that belong to the actual number. Do not truncate it just to meet the limit. If the original number itself exceeds 35 characters, ask your software supplier how to resolve the reference without identifying a different invoice. Check the file again after correcting it.
